This machine comprises an automatic weighing means, a packing n'ieans, a can conveying or carrying means. and clutch and cam mechanisms, all so connected and timed, that a plurality of cans, or other containers, may be ra )idly and successfully with a pre etermined amount of powder, as will now appear.

In the preferred construction, shown in the drawing., the machine comprises three complete weighing. packing and can conveying mechanisms, all ot' which are under the. control of one set of operating' means, but for the sake of clearness, only one unit and its coacting' olieiating` means will be de` 1scribed in detail, it being understood that the other units are duplicates, and that as many other units as may he desired, may be added to the machine at will.

The machine is of the general shape and construction best shown in Figs. 1, 2 Jand 3 of the drawings, and is provided with the side frames A and B held together by the truss beams such as C and i), and the top or bed plate E, (Fig. 4).

Mounted on any suitable support, at tached to the top plate E of the machine is a feed hopper 1, (see Figs. 1, (i, 7 and' 8) which is adapted to receive powder or other material to he weighed and packed by the machine. Any suitable agitating means 2 to facilitate the feeding of the powder, may be mounted within the hopper and driven from any convenient source of power. This hopper is preferably provided at its discharge en "t with two rock shafts 3 (Figs. S and 7) on which are mounted the cut-oft gates 4. Short arms rigidly mounted on the ends ot' the rock shafts 3 are' ivot.- ally connected to the toggle levers 6 and 7, the lever 7 being extended beyond the mov` ahle stud S connecting said levers. and vterminating in a weight 9. This stud 8 is of suttieient length to extend en its inner end between the guides 10, and has freely mounted on its outer end an anti-friction roller 11, which consequently travels in a ve tical plane hy reason of said stud S and guides l0. A trip trigger 12 is pivotally mounted on a stud 113 which is located below the roller 11 and approximately =in the vertical line in which the said roller travels. This trigger 12 is preferably of the construction shown, and is pro.'ided with the shortl Weighted arms 14 and a longer weigl'ited arm- 15, which arm 15 has pivotally mounted 0n its outer end a strip yoke 1G.

The mechanism just described is known as the powder feed mechanism and is automatically controlled by the scale mechanism, which latter also controls the other movements of the machine which are in synchro-- main power shaft 1S which is driven by the pulley 19.

20 indicates a spur g vtion rigidly fixed on the power shaft 18, witch transmits power to the spur gear 21, loosely mounted on the clutch shaft 17. The spur gear 21 is provided with a series of clutch pockets 22 on its inner face Figs. 5 and il) which pockets are adapted to receive the driving end of a pawl 23, which is pivotally mounted in the lug 24, carried by the` spur gear 25. tast on the clutch shaft 17. Consequently, the spur gear 21, pawl 23, and spur gear 25, constitute a clutch which imparts motion to the ehitch shaft. 17, but'of course any other suitable connection may be pro-- fheatn 27 which carries on one end the weigh-
